0-5 Foreword This Manual is designed primarily for use by trained mechanics in a properly equipped shop. However, it contains enough detail and basic information to make it useful to the owner who desires to perform his own basic maintenance and repair work. A basic knowledge of mechanics, the proper use of tools, and workshop procedures must be understood in order to carry out maintenance and repair satisfactorily. Whenever the owner has insufficient experience or doubts his ability to do the work, all adjustments, maintenance, and repair should be carried out only by qualified mechanics. In order to perform the work efficiently and to avoid costly mistakes, read the text, thoroughly familiarize yourself with the procedures before starting work, and then do the work carefully in a clean area. Whenever special tools or equipment are specified, do not use makeshift tools or equipment. Precision measurements can only be made if the proper instruments are used, and the use of substi- tute tools may adversely affect safe operation. For the duration of the warranty period, especially, we recommend that all repairs and scheduled maintenance be performed in accordance with this service manual. Any owner maintenance or repair procedure not performed in accordance with this manual may void the warranty. To get the longest life out of your Motorcycle: • Follow the Periodic Maintenance Chart in the Service Manual. • Be alert for problems and non-scheduled maintenance. • Use proper tools and genuine Kawasaki Motorcy- cle parts. Special tools, gauges, and testers that are necessary when servicing Kawasaki motorcy- cles are introduced by the Special Tool Catalog or Manual. Genuine parts provided as spare parts are listed in the Parts Catalog. • Follow the procedures in this manual carefully. Don't take shortcuts. • Remember to keep complete records of maintenance and repair with dates and any new parts installed. How to Use this Manual In preparing this manual, we divided the product into its major systems. These systems became the manual's chapters. All information for a particular system from adjustment through disassembly and inspection is located in a single chapter. The Quick Reference Guide shows you all of the product's system and assists in locating their chapters. Each chapter in turn has its own compre- hensive Table of Contents. The Periodic Maintenance Chart is located in the General Information chapter. The chart gives a time schedule for required maintenance operations. If you want spark plug information, for example, go to the Periodic Maintenance Chart first. The chart tells you how frequently to clean and gap the plug. Next, use the Quick Reference Guide to locate the Electrical System chapter. Then, use the Table of Contents on the first page of the chapter to find the Spark Plug section. Whenever you see these WARNING and CAUTION symbols, heed their instructions! Always follow safe operating and maintenance practices. AWARNING This warning symbol identifies special instructions or procedures which, if not correctly followed, could result in personal injury, or loss of life. CAUTION This caution symbol identifies special instructions or procedures which, if not strictly observed, could result in damage to or destruction of equipment.

0-6 This manual contains four more symbols (in addition to WARNING and CAUTION) which will help you distinguish different types of information. NOTE o This note symbol indicates points of particular interest for more efficient and convenient operation. • Indicates a procedural step or work to be done. O Indicates a procedural sub-step or how to do the work of the procedural step it follows. It also precedes the text of a NOTE. •vindicates a conditional step or what action to take based on the results of the test or inspection in the procedural step or sub-step it follows. In most chapters an exploded view illustration of the system components follows the Table of Contents. In these illustrations you will find the instructions indicating which parts require specified tightening torque, oil, grease or a locking agent during assembly.

KLX650C, US EMISSION CONTROL INFORMATION To protect the environment in which we all live, Kawasaki has incorporated crankcase emission (1) and exhaust emission (2) control systems in compliance with applicable regulations of the United States Environmental Protection Agency and California Air Resources Board. Additionally, Kawasaki has incorporated an evaporative emission control system (3) in compliance with applicable regulations of the California Air Resources Board on vehicles sold in California only. 1. Crankcase Emission Control System This system eliminates the release of crankcase vapors into the atmosphere. Instead, the vapors are routed through an oil separator to the intake side of the engine. While the engine is operating, the vapors are drawn into combustion chamber, where they are burned along with the fuel and air supplied by the carburetion system. 2. Exhaust Emission Control System This system reduces the amount of pollutants discharged into the atmosphere by the exhaust of this motorcycle. The fuel and ignition systems of this motorcycle have been carefully designed and constructed to ensure an efficient engine with low exhaust pollutant levels. 3. Evaporative Emission Control System Vapors caused by fuel evaporation in the fuel system are not vented into the atmosphere. Instead, fuel vapors are routed into the running engine to be burned, or stored in a canister when the engine is stopped. Liquid fuel is caught by a vapor separator and returned to the fuel tank. The Clean Air Act, which is the Federal law covering motor vehicle pollution, contains what is commonly referred to as the Act's "tampering provisions." "Sec. 203(a) The following acts and the causing thereof are prohibited... (3) (A) for any person to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title prior to its sale and delivery to the ultimate purchaser, or for any manufacturer or dealer knowingly to remove or render inoperative any such device or element of design after such sale and delivery to the ultimate purchaser. (3) (B) for any person engaged in the business of repairing, servicing, selling, leasing, or trading motor vehicles or motor vehicle engines, or who operates a fleet of motor vehicles knowingly to remove or render inoperative any device or element of design installed on or in a motor vehicle or motor vehicle engine in compliance with regulations under this title following its sale and delivery to the ultimate purchaser..." (Continued on next page.)

0-4 NOTE o The phrase "remove or render inoperative any device or element of design" has been generally interpreted as follows: 1. Tampering does not include the temporary or rendering inoperative of devices or elements of design in order to perform maintenance. 2. Tampering could include: a. Maladjustment of vehicle components such that the emission standards are exceeded. b. Use of replacement parts or accessories which adversely affect the performance or durability of the motorcycle. c. Addition of components or accessories that result in the vehicle exceeding the standards. d. Permanently removing, disconnecting, or rendering inoperative any component or element of design of the emission control systems. WE RECOMMEND THAT ALL DEALERS OBSERVE THESE PROVISIONS OF FEDERAL LAW, THE VIOLATION OF WHICH IS PUNISHABLE BY CIVIL PENALTIES NOT EXCEEDING $10,000 PER VIOLATION. KLX650A/C, US TAMPERING WITH NOISE CONTROL SYSTEM PROHIBITED Federal law prohibits the following acts or the causing thereof: (1) The removal or rendering inoperative by any person other than for purposes of maintenance, repair, or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the vehicle after such device or element of design has been removed or rendered inoperative by any person. Among those acts presumed to constitute tampering are the acts listed below: • Replacement of the original exhaust system or muffler with a component not in compliance with Federal regulations. • Removal of the muffler(s) or any internal portion of the muffler(s). • Removal of the air box or air box cover. • Modifications to the muffler(s) or air intake system by cutting, drilling, or other means if such modifications result in increased noise levels.

1-2 GENERAL INFORMATION Before Servicing Before starting to service a motorcycle, careful reading of the applicable section is recommended to eliminate unnecessary work. Photographs, diagrams, notes, cautions, warnings, and detailed descriptions have been included wherever necessary. Nevertheless, even a detailed account has limitations, a certain amount of basic knowledge is also required for successful work. Especially note the following: (1) Dirt Before removal and disassembly, clean the motorcycle. Any dirt entering the engine or other parts will work as an abrasive and shorten the life of the motorcycle. For the same reason, before installing a new part, clean off any dust or metal filings. (2) Battery Ground (KLX650C) Remove the ground (-) lead from the battery before performing any disassembly operations on the motorcycle. This prevents: (a) the possibility of accidentally turning the engine over while partially disassembled. (b) sparks at electrical connections which will occur when they are disconnected. (c) damage to electrical parts. (3) Installation, Assembly Generally, instalaltion or assembly is the reverse of removel or disassembly. But if this Service Manual has installation or assembly procedures, follow them. (4) Tightening Sequence Generally, when installing a part with several bolts, nuts, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them evenly in a cross pattern. This is to avoid distortion of the part and/or causing gas or oil leakage. Conversely when loosening the bolts, nuts, or screws, first loosen all of them by about a quarter turn and then remove them. Where there is a tightening sequence indication in this Service Manual, the bolts, nuts, or screws must be tightened in the order and method indicated. (5) Torque When torque values are given in this Service Manual, use them. Either too little or too much torque may lead to serious damage. Use a good quality, reliable torque wrench. (6) Force Common sense should dictate how much force is necessary in assembly and disassembly. If a part seems especially difficult to remove or install, stop and examine what may be causing the problem. Whenever tapping is necessary, tap lightly using a rubber, wooden or plastic-faced mallet. Use an impact driver for screws (particularly for the removal of screws held by a locking agent) in order to avoid damaging the screw heads. (7) Edges Watch for sharp edges, especially during major engine disassembly and assembly. Protect your hands with gloves or a piece of thick cloth when lifting the engine or turning it over. (8) High-Flash Point Solvent A high-flash point solvent is recommended to reduce fire danger. A commercial solvent commonly available in North America is Stoddard solvent (generic name). Always follow manufacturer and container directions regarding the use of any solvent. (9) Gasket, O-Ring Do not reuse a gasket or O-ring once it has been in service. The mating surfaces around the gasket should be free of foreign matter and perfectly smooth to avoid oil or compression leaks. (10) Liquid Gasket, Non-Permanent Locking Agent Follow manufacturer's directions for cleaning and preparing surfaces where these compounds will be used. Apply sparingly. Excessive amounts may block engine oil passages and cause serious damage. An example of a non-permanent locking agent commonly available in North America is Loctite Lock'n Seal (Blue). (11) Press A part installed using a press or driver, such as a wheel bearing (hub bearing), should first be coated with oil on its outer or inner circumference so that it will go into place smoothly. (12) Ball Bearing, Needle Bearing Do not remove a ball bearing or a needle bearing unless it is absolutely necessary. Replace any ball or needle bearings that were removed with new ones, as removal generally damages bearings.

GENERAL INFORMATION 1-3 Install bearings with the marked side facing out applying pressure evenly with a suitable driver. Only press on the race that forms the press fit with the base component to avoid damaging the bearings. This prevents severe stress on the balls or needles and races, and prevent races and balls or needles from being dented. Press a ball bearing until it stops at the stop in the hole or on the shaft. (13) Oil Seal and Grease Seal Replace any oil or grease seals that were removed with new ones, as removal generally damages seals. When pressing in a seal which has manufacturer's marks, press it in with the marks facing out. Seals should be pressed into place using a suitable driver, which contacts evenly with the side of seal, until the face of the seal is even with the end of the hole. Before a shaft passes through a seal, apply a little high temperature grease on the lips to reduce rubber to metal friction. (14) Circlip, Retaining Ring Replace any circlips and retaining rings that were removed with new ones, as removal weakens and deforms them. When installing circlips and retaining rings, take care to compress or expand them only enough to install them and no more. (15) Cotter Pin Replace any cotter pins that were removed with new ones, as removal deforms and breaks them. (16) Lubrication Engine wear is generally at its maximum while the engine is warming up and before all the rubbing surfaces have an adequate lubricative film. During assembly, oil or grease (whichever is more suitable) should be applied to any rubbing surface which has lost its lubricative film. Old grease and dirty oil should be cleaned off. Deteriorated grease has lost its lubricative quality and may contain abrasive foreign particles. Don't use just any oil or grease. Some oils and greases in particular should be used only in certain applications and may be harmful if used in an application for which they are not intended. This manual makes reference to molybdenum disulfide grease (M0S2 ) in the assembly of certain engine and chassis parts. Always check manufacturer recommendations before using such special lubricants. (17) Electrical Wires Ail the electrical wires are either single-color or two-color and, with only a few exceptions, must be connected to wires of the same color. On any of the two-color wires there is a greater amount of one color and a lesser amount of a second color, so a two-color wire is identified by first the primary color and then the secondary color. For example, a yellow wire with thin red stripes is referred to as a "yellow/red" wire; it would be a "red/yellow" wire if the colors were reversed to make red the main color. (18) Replacement Parts When there is a replacement instruction, replace these parts with new ones every time they are removed. These replacement parts will be damaged or lose their original function once removed. (19) Inspection When parts have been disassembled, visually inspect these parts for the following conditions or other damage. If there is any doubt as to the condition of them, replace them with new ones. Abrasion Crack Hardening Warp Bent Dent Scratch Wear Color change Deterioration Seizure (20) Specifications Specification terms are defined as follows: "Standards" show dimensions or performances which brand-new parts or systems have. "Service Limits" indicate the usable limits. If the measurement shows excessive wear or deteriorated performance, replace the damaged parts.
